具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图及实施例对本发明作进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
一种用于农作物的筛料机构，如图1-4所示，包括支架1、筛筒2、固定轴3、端盖4、第一导料板5和驱动机构6，第一导料板5螺旋设置在固定轴3上，端盖4固定设置在第一导料板5的一侧，并且固定设置在固定轴3上，固定轴3固定架设在支架1上，筛筒2套设在第一导料板5外，并且与固定轴3转动连接，利用驱动机构6驱动筛筒2转动，筛筒2侧壁设置若干个筛孔21，端盖4上开设进料口。具体筛料方法为，将小麦从进料口倒入筛筒2内，通过驱动机构6驱动筛筒2转动，使得小麦在筛筒2内翻滚，使得小麦从筛孔21落下，而麦秆剩余在筛筒2内；同时利用第一导料板5引导筛筒2内的物料从左向右移动，并且从筛筒2的右端排出。进而实现小麦的筛分。
在一实施例中，如图1-4所示，端盖4凸起设置旋转槽41，筛筒2的一端通过轴承旋转设置在旋转槽41内，另一端通过支撑件22与固定轴3转动连接。筛筒2的两端均设置支撑点，保证筛筒2旋转的稳定性，并且减少对于第一导料板5的负载；假设筛筒2的两端不设置支撑点，第一导 料板5需要支撑筛筒2，这样会大大降低第一导料板5的寿命，并且使得第一导料板5与筛筒2之间的间隙越来越大。
在一实施例中，如图1-5所示，还包括导料罩7，导料罩7呈圆柱体空心筒状结构，并且在其侧壁上设置出料口，出料口向外延伸设置出料板71，导料罩7的一端与端盖4固定连接，另一端设置与导料罩7配合的通孔，并且通过轴承与筛筒2连接。使得导料罩7与筛筒2之间为滚动连接。
在一实施例中，驱动机构6包括伺服电机，伺服电机固定设置在支架1上，筛筒2外壁设置传动齿，伺服电机通过齿轮与传动齿啮合。
在一实施例中，第一导料板5与筛筒2接触的边沿设置胶条。以填补第一导料板5与筛筒2之间的间隙，防止长期使用后，第一导料板5与筛筒2之间间隙过大，造成无法很好的引导物料移动。
在一实施例中，如图1-7所示，还包括料斗8和上料机构9，上料机构9的出料口与端盖4的进料口连接，料斗8与上料机构9的进料口连接。通过料斗8暂存物料，避免上料机构9空转。即农民将存在麦秆的小麦倒入料斗8内，通过上料机构9将小麦送入筛筒2内，而将料斗8内的小麦完全送入筛筒2需要一段时间，利用这段时间再将小麦搬运过来倒入料斗8内，巧妙运用上料时间，来及时补料，提高了筛料效率。
优选的，如图1-7所示，料斗8的底板向上料机构的进料口倾斜。
在一实施例中，如图1-7所示，上料机构9包括输料管91、转动轴92和驱动电机93，输料管91竖直设置，其上端设置出料口，下端设置进料口，转动轴92同心设置在输料管91内，转动轴92侧壁螺旋设置第二导料板94，驱动电机93设置在输料管91上方；驱动电机93可以是伺服电机，利用驱动电机93驱动转动轴92带动第二导料板94转动，以将小麦向上提升。
本发明的筛料机构适用范围包括但不限于小麦、芝麻、稻谷。
以上仅为本发明的较佳实施例，并非用来限定本发明的实施范围；如果不脱离本发明的精神和范围，对本发明进行修改或者等同替换，均应涵盖在本发明权利要求的保护范围当中。
